To all whom a: may concern.

Be it known that we, ELMER E. KILMER and FRED P. Gno'rrr, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, having jointly invented certain new and useful Improvements in VVire-Block Strippers, do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanying drawings, in which the same reference letters refer to the same or similar parts.

In the accompanying drawings which illustrate embodiments of the several features of our invention, Fig. 1 is a side view showing the stripping-reel in positionon a revoluble block; Fig. 2 is a similar View showing the stripping-reel in position above a feeding reel; Fig. 3 is a top plan view of the stripping-reel;. Fig. l is a sectional view on the line 4& in Fig. 3 showing the stripping-reel in place on one of the blocks; and Fig. 5 is similar view showing the stripping-reel collapsed to drop a coil of wire on a feeding-reel.

Our invention consists in the matters hereinafter described and then pointed out in the appended claims, and the present application is a division of our co -pending application filed September 15, 1921, bearing Serial Number 501,008.

In. the drawings the reference letter A indicates a draw bench or frame on which are located die-boxes or draw-plates B through which the wire is drawn from suitable feeding-reels (1 by the revolving drums or blocks D, disposed along the bench in the usual relation to the. dies and revolved by the usual mechanism located under the bench including a suitable clutch to connect and disconnect it to each block; only one block is shown, but it is understood that as many may be employed as desired. In the operation of the parts as heretofore constructed the wire is drawn through the first die-box B onto the revolving block D, and after the block is stopped the drawn coil is stripped over its top by the manual labor of the operator who then lifts it away from the bench or places it upon a feeding-reel from which it is drawn through a. second die box B to the second revolving block D, and the above manual operations are then repeated; if a third drawing is necessary to reduce the wire to the desired diameter the coil s placed by the operator on a second feeding-reel from which it is drawn through a third die-box B to the third revolving which the drawn wire coiled as the block revolves, and when the block is stopped a conveyer automatlcally lifts the reel and its constructed to receive a stripping-reel upon coil from the block and transfers them to another feeding reel for a subsequent drawing or .to a pile or truck after the drawing. As shown the blocks D are conical in con tour and are provided with a series of slots (Z in the outer faces of their bodies and in the upper faces of their flared rims d.-

The stripping-reels E are composed of upper open-end drunms e slightly smaller in diameter than the bodies of the blocks in order to rest thereon, and legs 6 intermediately pivoted at e in the outer ends of the crossarnrs or spider e fastened on the interior of the drum. The legs depend below the drum and are bent outwardly below their pivots through apertures in its lower edge, and their lower portions are inclined outwardly from this point to correspond with the tapcr of the block and terminate in radially projecting or outwardly flared feet 0*; the legs on each reel corre spond 'in' number and circumferentially spaced relation with the slots in the blocks, so that when a reel is in place on the block its legs and feet will he in the slots and grooves of the block with their exposed surfaces flush therewith as shown in Fig. 4, and the wire will be wound around the outer edges. of the legs and will rest upon the outwardly flared feet. The upper ends of to a sliding collar or sleeve e which moves up and down on a stem or post 6 rigidly mounted on the spider or cross-frame c at the center of the drum; the sleeve is prevented from turning on the post and its reciprocation thereon is limited by a closed slot 6 therein engaging a pin 6 on the post, and the sleeve is provided with a suitable shackle. or eye 6 at its upper end'to receive a suspending hook on on a conveying cable or chain M. When a stripping-reel the legs are connected by pivoted links .v

.and comprising aclrum carrying a. central hangs by its eye or shackle the weight of the drum will slide the sleeve up to its raised position at the upper end of the post, and this draws the upper ends of the legs inwardly and throws their lower ends outwardly, so that: if thereel is then lowered into position on a block its legs and feet will enter the slots of the block and lie flush with its outer pontions. When the shackle is released with the reel off the block the sleeve slides: down the stem and throws the legs inwardly as shown in Fig. 5 thereby releasing the coil of wire from the reel, and as the movement of the sleeve on its stem is long enough to withdraw the feet inwardly within the circumference of the drum the coil will drop or passoff the 7 reel.

When the coil of wire on the stripping- .reel is to be given a further drawing it is )lIISZJGGl,islOWeld to the underneathfeedingsreel andthe tension of the hanger chain M is released from the shackle 6 the spider c rests on the head 0 and the sleeve-c drops onits stem, and as the distance from the pivots of the legs'e to their feet is less than that from the head 0 to the base 0 the legs of thestripping-reel collapse inwardly and the coil is, then supported onthe'feeding-reel ready forthe second drawing, the strippingreel being then readily withdrawn from the coil. A second stripping-reel being mounted on a block D, the end of the coil from. the reel/C is passed through the corresponding die and attached to thisblock which. is then revolved. The operations above described are duplicated until the coil on the second stripping-reel is released therefrom. It a ;t.hir drawin is desired a. thirdstri 3 )in l: U

reel is mounted 011 a block D, and the operations are repeated. At the end of any drawing the reeland its (3011 may be deposited on a truck or pile, and when the tension of the hanger on its shackle is released the reel collapses and dumps the coil.

We claim:

1. In a device of the class described, a

wire-coiling block, a stripping-reel constructedto receive thewire coiled on the block vertical stem, a reciprocating sleeve on the stem, legs pivoted in the drum and constructed with coil-supporting ends projecting below the drum, andlinks 'pivotally connecting the upper ends'of the legs to the sleeve to expand their lower ends to the contour of the block when the sleeve is raised on its stem and to collapse them when ally connecting the upper ends of the legs to the sleeve to expandtheir lower ends into the seats when the sleeve is raised on its stem and; to collapse them when the sleeve is lowered.

S. In av device of the class described, ,awire-coiling block having. seats in its periphery, and a stripping-reel comprising a drum constructed to seat upon the block, a spider mounted in the drum and carrying a central. vertical stem, a sliding sleeve on the stem having a pin and slot connection therewith, legs pivoted on the spider and constructed with coil-supporting ends project ing below the drum, and links pivotally connecting the upper ends of the, legs to the sleeve to expand their lower ends into the seats of the drum when the sleeve is raised on its stem and to. collapse them when the sleeve is lowered.

4. In a device of the class described, a feeding-reel having a. base and a skeleton frame, and a stripping-reel comprising a drum, a spider mounted-in the drum and carryinga central vertical stein, a sliding radially expand and collapse-the-legs, and

a feeding-reel having a base and a skeleton frame extending above its base a distance greater than the length of the legs, whereby when the stripping-reel is seated on the frame of the feeding-reel its legs will col- 'la-pse within the area of the base.

In testimony whereof we affix our signatures.
